In music, a term not commonly used by composers, but made famous by Bach in his 15 Inventions for keyboard 1720. In two parts, each composition is contrapuntal and highly imitative, based upon a short melodic motif or phrase. Bach’s so-called “three-part inventions” were not named as such by the composer, but rather the term “sinfonia” was used instead (15 Sinfonias 1723).
